"BVLOS" has too broad of a definition for a simple 3 question answer.
BVLOS is safe under the right conditions, and very unsafe under the wrong conditions. We see range tests of multiple miles or kilometers that are most certainly unsafe. And we see some that are relatively safe.
FPV is its own category. Flying FPV around your backyard, or at a local park with very few people is safe. But technically it's illegal and unsafe. Flying FPV can also be unsafe. I know someone who flies long range FPV wing foamies and it's safe.
BVLOS for many of our uses is also safe. I believe there isn't a single drone operator out there who's been flying for more than a few months that can say they've never flown BVLOS. I have. And I make no bones about it. But I do it safely.
It's safe because I have 100% command of the airspace around me, and I use a VO. Yesterday I won't say how far I flew, but my VO and I definitely did not have "eyes" on my
Mavic 3. But we were literally over a huge open cow pasture that is soon to be turned into a reservoir, about 60 miles East of Denver. There was not a sole around except me, my VO, and the clients. And cows, but they don't count.
So there was no danger to anyone on the ground, nothing around to run into at 400' (the tallest structure was a dilapidated windmill at around 75'), and we had 360° situational awareness of the airspace so there was no danger of manned aircraft. We had to cross I-70 at one point when BVLOS, so I pointed the gimbal down and played "Frogger". And that wasn't even really necessary. The interstate was so empty that the likelihood of my flying over someone in one of the vehicles that went by were infinitesimal.
So, is BVLOS safe?
I thinks it's multitudes safer that the FAA wants us to believe, but I think it's much more dangerous than many newbies and hotshots act like it is.
